Fuel information
Gasoline engine
Your vehicle must use only unleaded gasoline.
Select octane rating 87 (Research Octane Number 91) or higher. Use
of unleaded gasoline with an octane rating lower than 87 may result
in engine knocking. Persistent kno cking can lead to engine damage.
At minimum, the gasoline you use should meet the specifications
of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
Flex-fuel engine
Your vehicle must use only unleaded gasoline, E85, or a blend of the
two fuels.
Unleaded gasoline (Octane rating 87 [Research Octane Number 91]
or higher), E85, or a blend of these two fuels is required for optimum
engine performance.
The use of unleaded gasoline with an octane rating lower than 87
may result in engine knocking. Persistent knocking can lead to
engine damage.
The use of fuel with an ethanol concentration in excess of 85% will
have a negative impact on drivi ng performance and can cause dam-
age to the fuel system components.
At minimum, the gasoline you us e should meet the specifications
of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
At minimum, the E85 you use should meet the specifications of
ASTM D5798 in the U.S.A.

■Toyota recommends the use of gaso line containing detergent additives
● Toyota recommends the use of gasoline that contains detergent additives
to avoid build-up of engine deposits.
● All gasoline sold in the US contains detergent additives to clean and/or
keep clean intake systems.
■ Toyota recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxy-
genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in
many areas.
Toyota recommends the use of cleaner burning gasoline and appropriately
blended reformulated gasoline. These types of gasoline provide excellent
vehicle performance, reduce vehicle emissions and improve air quality.
■ Toyota does not recommend blen ded gasoline (Gasoline engine)
● If you use gasohol in your Toyota, be sure that it has an octane rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methanol.
●Use only gasoline containing a maxi-
mum of 10% ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 10% etha-
nol, including from any pump labeled
E15, E30, E50, E85 (which are only
some examples of fuel containing more
than 10% ethanol).DO NOT use gasoline
containing more than
10% ethanol.
(15% ethanol)
(50% ethanol) (85% ethanol)

■
Toyota does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your Toyota dealer for service.
■ Toyota does not recommend blended gasoline (Flex-fuel engine)
Do not use non-specified fuels such as the following.
• Fuels containing methanol.
• Fuels with more than 85% ethanol.
■ Toyota does not recommend the use of after-market fuel additives
(Flex-fuel engine)
Do not use any after-market fuel additives when repeatedly refueling with
E85, as some after-market fuel additives are not compatible with E85.
NOTICE
■ Notice on fuel quality
●Do not use improper fuels.
If improper fuels are used, the engine will be damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Gasoline engine: Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Use of unleaded gasoline with an octane rating lower than 87 may result in
engine knocking. Persistent knocking can lead to engine damage and
should be corrected by refueling with higher octane unleaded gasoline.
